TURBINE FOR ORGANS 0R THE LIKE.

Application filed September 12, 1925. Serial No. 55,970.

To all whom t may concern.'

Be 1t known that` I, ANTOINE LAMON- TAGNE, subject of the King of GreatB1 itain,

residing at Montreal, Province of Quebec, Canada, have invented certainne w and useful Improvements in Turbines for Organs or the like; and Ido hereby declare that the following is a full, clear, and eXactdescription of the invention, such as will enable others skilled in theart to 'which it appertains to make and use thesame.

The present invention pertains to a novel turbine for organs, althoughit may also be used in other installations where the functions of thedevice may be used.

In the present organ constructions, a high pressurei'or the pipes isobtained by mounting two or more rotors for the purpose of imparting therequired. compression to the air driven thereby. In the operation ofsuch a system, the air is driven from one rotor to the other,successively gaining in com-pression.

The object of the present invention is to eliminate the necessity of aplurality of rotors for creating the desired high `pressure. This objectis accomplished by constructing the rotor casing in such a manner thatthe rotor itself is contained in two separate compartments. `One ofthese compartments receives the air which is compressed by half of therotor to the maximum compression obtainable by the rotor. The partitionsdividing the compartments are so ported that the compressed air drivenby the rst half of the rotor is delivered to the second half Vby Whichit is doubled in pressure and thus render suitable for high pressurepurposes. Incidental to the reduction in the number of rotors necessaryfor high pressure, the fixed or anchorto. support a plurality of rotorsare. materially reduced in number.

A further feature of the invention is the provision of a secondaryoutlet formed in the rotor casing in such a manner as to receive airunder the first stage of compression by the'rotor. This airis suitableforl ordinary purpose, but the secondary outlet for supplying itdesired, thus limiting the apparatus tothe productionof air under highpressure, or

using both outlets for two diiferent presmay be blocked if vwhich isconcentric with following description and in the accompany-` ingdrawings in which;

Figure 1 is a vertical section of the device; Figure 2 is a perspectiveview of the apv paratus;

Figure 3 is a perspective view of the separator disc surrounding therotor;

Figure 4 1s a perspective view of the out- -let section of the turbinecasing;

Figure 5 is a perspective view of the intermediate section of theturbine casing; and

Figure 6 is a perspective view of the inlet section of the turbinecasing.

Reference to these views will novT be made by use of like characterswhich are employed to designate corresponding parts throughout.

The motor 1 for driving the rotor of the turbine is disposed within amotor boX 2 having air ducts 3 for the intake of air required by therotor. The ducts are provided with doors 4 suitably mounted on hinges 5Vso that they will open when a depression within the motor box occurs.

The shaft 6 of the motor carries a rotor 7 disposed within a casingconsisting of three sections, the inlet section 8 being secured to theopen slide of the motor box on ears 9 projecting from the latter. Thewall 10 of this ysection which covers the open side of the motor box hasan air port 11 establishing communication between the motor box and therotor casing. An intermediate section 12 is secured to the inlet section8, and a partition 13 is interposed between the two sections. Thispartition has a circular opening 14 within which the rotor turns. Thepartition is disposed in a plane parallel to a diameter of the rotor andlies lin the particular plane that bisects the rotor blades 15 radiallywith respect to the rotor unit. This partition furthermore has its lowercorners cut oif as indicated by the numeral 16 in Figure 3, whereby thefluid driven from the rotor may flow from the inlet section 8 throughthe spaces formed by the cut-away corners in the manner described below.

The base 17 of the lintermediate section 12 has its lower corners cutaway as at 18 in alinement with the cut off corners 16 of the partition13. The corners 18 are also bridged by integral corner plates 19,forming a conduit in continuation with the spaces 16. The base 17 has anopening 20 the rotor. Finally,

The outlet section 22 is Secured to the intermediate section and isformed with an v outlet port 23 opposite the open corners 21.

' When it is desired to'use the rlhis section contains an internaldividing wall 24 which engages the base 17 of the section 12 in such amanner as to separate the opening 20 from the outlet 23. On the otherside of the dividing wall, the outlet section has a second outlet port25 which is closed by a cover plate 26 when not in use. second outlet 25for the purpose stated below, the cover plate lis removed and a pipe 27is secured over the outlet 25 as illustrated in dotted lines in Figurel.

The operation of the device is as follows: During the rotation of theotor, air is drawn through the ducts 3 in o the motor box 2, and thencethrough the inlet port 11 to the inlet section 8. l The airis acted uponby one half of the rotor, namely, the haltl lying at the inlet side otthe partition 13. This air is driven through the spaces iormed thecut-away corners 16, beneath the plates 19 and through the cut-awaycorners 18 of the intermediate section 12 to the outlet section 22. Whenthe second outlet port 25 is closed, the air is drawn through thecentral opening 20 of the base 17 and to the half of the rotor disposedwithin the intermediate section. The air being previously under pressurereceived at the first halt' of the rotor'is now' increased to doublethis pressure by the second half of the rotor. Finally, the doublycompressed air passes through the open corners 21 of the base 1'7 and tothe outlet 23. 'In this manner there is provided at the outlet 23 asupply o air of twice the pressure that can ordinarily be delivered bythe rotor'. The apparatus therefore makes possible the production of apressure which would ordinarily require two rotors of the size actuallyemployed. Since such a high pressure is often required in the operationof organs, the two rotors ordinarily necessary in such cases may bereplaced by a single rotor of the same type if the casing is constructedin the manner setforth.

For obtaining air at low pressure, that is, air at the rst stage ofcompression, the cover plate 26 is removed and a pipe 27 is v connectedto the second outlet 25.-

While a specific embodiment of the invention has been illustrated anddescribed, it is to be understood that various alterations in thedetails of construction may be made without departing from the spirit ofthe invention as indicated by the appended claims.

Having thus fully described the invention, what I claim as new anddesire to protect vby Lettersfatent is 1.
